Hiding UITableViewCell

Question

Is there a way to hide a UITableView cell? I'm looking for some property or method I can invoke on the UITableViewCell returned by a synchronous cellForRowAtIndexPath() to hide it and make it unselectable by the user.

Answer 1

You mean to leave a gap in the table where the cell should be, or just to progress from the one before it straight to the one after it? In the former case, I guess you might try getting the cell's contentView and set its hidden property to YES; otherwise, you'll just have to do a little logic in your -tableView:numberOfRowsInSection: and -tableView:cellForRowAtIndexPath: methods, returning (the number of cells you'd otherwise return - 1) from the first, and, depending on whether the row index is less than or greater than the row you're not including, either (the cell you'd otherwise return) or (the cell at (the row index + 1)), respectively.

(edit, because the explanation was convoluted:)

- (NSInteger)tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section
{
    if(section == theSectionWithoutARow)
    {
        if(shouldRemoveTheRow)
            return [theArrayWithTheSectionContents count] - 1;
        else
            return [theArrayWithTheSectionContents count];
    }
    // other sections, whatever
}

- (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // blah blah standard table cell creation

    id theCellObject;

    if(indexPath.section == theSectionWithoutARow)
    {
        NSInteger theActualRowToDisplay = indexPath.row;
        if(shouldRemoveTheRow && indexPath.row >= theRowIndexToRemove)
        {
            theActualRowToDisplay = indexPath.row + 1;
        }
        theCellObject = [theArrayWithTheSectionContents objectAtIndex:theActualRowToDisplay];
    }

    // now set up the cell with theCellObject

    return cell;
}
